In the following specification and the ac- 2 companying drawings I have set forth one embodiment of the invention. It will be understood, however, that modifications may be resorted to within the spirit and scope of the invention.

In the accompanying drawings:

Fig. 1 is an elevation of the bracket, applied to a post. I

Fig. 2 is a detail plan view partly in section, showing the upper fastenings and clamp.

Fig. 3 is a section on line 3-3, Fig.1, certain parts being in full-lines; and

Fig. 4 is a side view illustrating the man ner in which the brackets may be folded.

A fragment of a post such as commonly used in construction of gas tanks, oil tanks, and other scaffolds used for erection purposes, is shown at 1 to illustrate the manner of use of the bracket which is shown applied thereto.

My improved bracket is of metal and is complete and self contained, ready for attachment to any post such as that shown at 1. The bracket has an arm 2 and a brace 3 which are of angle iron construction for purposes of strength, the two being jointed together on a screw bolt 4.

plank, "it being understood that the plank runs from a bracket on one post to a corresponding bracket on. another post in the usual manner. r

The arm 2 and brace 3 are detachably and adj ustably secured to the post by clamps of the construction shown in Figs. 2 and 3.

The slots 15 are provided in the arm 2 and brace 3, and the series of holes 16 are provided in brace 3 to afford adaptability for adjustment of the clamp bolts 6. The nuts 9 are employed.

The bolts 6 are J shape, being provided with hooks 7 which are adapted to snugly embrace the horizontal webs of the arm 2 and brace 23 in the manner clearly shown in Figs. 2 and 3 and there are provided the upper and lower clamp plates 17 and 18 which lie on the opposite side of the post 1 from the arm and brace, respectively. The shanks of the J-shaped bolts 6 lie against the webs of the angle-irons which their hooks 7 embrace, thus strengthening said shanks and preventing slippage of the hooks 7'.

The left hand upper bolt 6 passes through a hole in the Vertical Web of the arm 2. The right hand bolt 6 passes-through a slot in the upper plate 17.

The left hand bolt 6 for the brace 3 passes through a slot 19 and the right hand bolt for f the brace 3 passes through a hole 20.

The plates 17 and 18 afford wide surfaces to clamp against the face of the post and they also provide broad bearing surfaces for the nuts 9 to work against. The vertical webs of the arm 2 and brace 3 bear firmly against the post.

The clamp bolts being disposed trans versely of the arm and brace and there being two in each instance, the bracket will sup- 1 of as well as lie against the webwhich is embraced by the hook, the bracket is firmly held in position against the post, without any possibility of wabbling.

I claim:

In a post bracket, the combination with an arm of angle-iron, of a brace therefor which is of angle-iron, and means forindependently securing the arm and the brace to a post, comprising in one instance J-shaped screw bolts whose shanks pass through one web of the brace and in the other instance J-shaped I screw bolts whose shanks pass through one web of the arm, said screw bolts each having a hook at one end and a nut at the other end the hooks snugly cmbracing a web of arm and brace and the shanks lying against the webs embraced by the hooks and clamp plates through which the nut-carrying ends of the bolts pass.

In testimony whereof I aflix my signature.
